According to the oclet rule an atom with two electron shells is most stable when it contains eight?

The octet rule is a simple rule of thumb that states that atoms tend to combine in such a way that they each have eight electrons in their valence shells, giving them the same electron configuration as a noble gas. The rule is applicable to the main-group elements. In simple terms, molecules or ions tend to be most stable when the outermost electron shells of their constituent atoms contain eight electrons.

The general rule is that full shells are more stable than partially filled shells. Since 2 electrons can go into the s subshell, and 6 into the p subshell, when the outer shell contains 8 electrons it makes the most stable configuration. (The d subshell actually is higher in energy than the next higher p and s subshells).

Explain why some elements are stable on their own while others are more stable in compounds?
its because some are naturally stable like helium, when some like hydrogen have an extra electron in their electron clouds. That's why they are unstable. When they meet with an element with one extra electron they can be stable because the first electron cloud holds 2 electrons. ex. : hydrogen - 1 electron hydrogen - 1 electron adding both together will give you a full eletron cloud. Hope this helps!
Why won't stable elements react?
Stable elements do not react because they don't need to. Elements react so that they can gain stability( as stability is gained by filling the outer most shell of the atom). As stable elements already have full outer shells and are stable , they do not react.
What is tin as a stable electron configuration?
Tin has 4 valence electrons. Because of this, Tin needs to lose the 4 electrons to make it stable. Thus the answer is SN4+
The octet rule indicates that?
In chemistry, the octet rule states that an atom has eight electrons in its outer shell. When all eight electron orbitals are filled, the atom is described as non-reactive. Examples include neon and argon.
How is carbon dioxide formed?
====================================== My explaination will be Carbon,the non-metal element that contains of 6electrons,2.4 .....the positive charge 4 valenced electrons will share its electron with 2 oxygen atoms that consists of 4 valenced electrons too,in order to achieve stable octet electron arrangement,thus CO2 is formed
What is characteristic about the outer electron shells of the halogens?
The outer electron shells of the halogens contain seven electrons, and need one more electron to have eight and become stable.
What are stable electron configurations are likely to contain?
completely filled valence shells
Noble gases are very stable because their outermost electron shells contain the maximum number of electrons that those outermost shells can possess?
Noble gases are very stable because their outermost electron shells contain the maximum number of electrons that those outermost shells can possess. This is a correct statement. Yes.
When is an element not likely to react?
When it is stable. that is, all of it's electron shells are fully occupied.
What is more stable partially filled or full electron shells?
Atoms with full outer electron shells are more stable. The atoms (elements) with full outer electron shells are the noble (sometimes called inert) gases. These are the elements in Group 18 of the periodic table, and you know them as helium, neon, argon, krypton, exnon and radon.
Explain what atoms are trying to achieve in there electron shells when they bond with each outher?
Atoms are trying achieve a stable electronic configuration i.e., stable arrangement of electrons in their electron shells. All configurations are not stable. Mostly stable configuration is attained by forming an octet of electrons in outer most shell. Sometimes octet rule is violated also.
How many shells in sodium?
the sodium atom has 3 shells where 2 electrons are in the first shell, 8 in the second and 1 in the third shell; which isn't stable..... and its symbol is Na :)
What is the chemical behavior of atoms whose outer electron shells contain 8 electrons?
These atoms are very stable and unreactive.
What are stable electron configurations most likely to contain?
filled energy sublevels
How many extra valence electrons does helium need to become stable?
Helium has 2 valence electrons and has completely filled orbitals / shells and helium is stable.
When chlorine gains an electron what achieves a complete octet?
when chlorine gains an electron, it now now contains a full octet. this means that the chlorine element is now chemically perfect and now is stable , but not as stable as one of the Noble Gases
Why is lithuim not a stable ion?
Lithium is not a stable ion due to its place on the periodic table. It is part of Group I, which has ions that lack full electrons shells. It would need two electrons instead of just the one it has for a full electron shell to be considered stable.
